An experiment was performed to test whether alcohol intoxication leads to cognitive disinhibition as measured by the Color Word Test. In psychoanalytic terms, it was hypothesized that alcohol would decrease secondary process functioning leading to disinhibition and so make it easier to perform a primary process function. 24 men and 24 women participated and were randomly assigned to an Alcohol group, a Placebo group or a Control group. The alcohol dose was 1.0 ml of 100% alcohol/kg body weight. No statistically significant differences were found on any of the three dependent measures, number of errors, number of hesitations and total time needed, except that men in the Alcohol group needed significantly longer time to complete the test. These results indicate that cognitive disinhibition is not valid as an explanation for alcohol-related changes in cognitive functioning.
进行了一项实验，以测试酒精中毒是否会导致如通过颜色词测试所衡量的认知去抑制。用精神分析的术语来说，假设酒精会降低次级过程功能，导致去抑制，从而使执行初级过程功能变得更容易。24名男性和24名女性参与了实验，并被随机分配到酒精组、安慰剂组或对照组。酒精剂量为每公斤体重1.0毫升100%酒精。在三个因变量指标上，即错误数量、犹豫次数和所需总时间，均未发现统计学上的显著差异，只是酒精组中的男性完成测试所需的时间明显更长。这些结果表明，认知去抑制并不能有效地解释与酒精相关的认知功能变化。
